There is a scene where Edward and Bella are sitting under some branches and its raining. Hard. In actuality it was not raining when they did the scene. They had to provide some man made rain for the scene. Edward looks totally soaked with water running off his hair and face. On the other hand, Bella seems quite dry in the scene. Its a little Twilight magic. The scene location for this was back off from the river and up under a cliff area which was covered in trees, ferns and grasses. Our guide at The Shire did mention that they had to build a lightweight structure to protect them and achieve the look they wanted for the scene. Here is the area where it was filmed. It is now more over grown.
